Splunk AppDynamics On-Premises Virtual Appliance

Splunk AppDynamics On-Premises Virtual Appliance referred as Virtual Appliance, offers robust solution to package, deploy and operate the Splunk AppDynamics software. This is a self-hosted deployment that reduces the onboarding time by streamlining the process. Virtual Appliance packages compatible versions of Splunk AppDynamics services, such as, Controller, Events, and End User Monitoring. Splunk AppDynamics components are containerized and deployed as Kubernetes®(K8s) services packaged with the Virtual Appliance image.

Virtual Appliance supports add-on features such as:

These add-on services are available for your environment based on your license agreement.

The following Splunk AppDynamics components are available along with the other infrastructure services:
